What I claim as my invention and desire Inthe body ofthe connecterl, depressions to secure by United States Letters Patent 8 are provided extending inwardly from the is e 40 internal surface of the metal sheet providing 1. A connecter for electric lels consisting it, and lugs 10 are cut in said sheet for the of a metal sleeve forming at e end a seat Hereinafter described purpose.

To arrange connecter on the end of cable ing with a cross ed e at its vfront end and a 5 or lead, a ree portion-.of the conducting wire resilient tongue proJecting within said sleeve i of the cable is wound on its insulating sheath Into said opemng opposite said cross edge andfor said lead and having a longitudinal openadapted to bear on a head of connected.

2. A connecter for electric leads consisting of a metal sleeve forming at one end a seat for said lead and having a longitudinal opening with a cross edge at its front end,A a resilient tongue projecting Within said sleeve into A said opening opposite said cross edge and adapted to bear on a head'of the part to be connected, and an abrupt projection on said resilient tongue for engaging an edgevof said part in a portion opposite its portion abutting against said cross edge.

3. A connecter for electric leads consisting of sheet metal rolled to form a sleeve,-said sleeve forming at one end a seat for `said lead and having a longitudinal opening cut therein, said opening being defined by two lateral projecting edges and a cross edge of the side walls of said sleeve at the ront end, and a resilient tongue projecting within said sleeve into said opening and extendingtowards said v cross`edge.

- 4. A connecter for electric leads consisting of sheet metal rolled to form a sleeve,

said sleeve forming at one end a seat for saidAv lead and having a longitudinal opening cut therein, said opening being defined by two lateral projecting edges anda cross edge at the front end, a resilient tongue projecting Within said sleeve into said opening and extending towards said cross edge, and an abrupt projection extending from said tongue opposite said cross edge.

In. testimony whereof I have signed myv name to this specification.
